Jheezzmearr J. Thompson was charged Nov. 3 with first-degree assault and second-degree criminal possession of a weapon, both felonies. He is accused of shooting Singleton once with a handgun and severely injuring her.

The Onondaga County Medical Examiner's Office completed an autopsy to determine Singleton's cause of death and if her death is directly related to her being shot, Helterline said.

"At this time, the results of the autopsy are not available," he said. "Detectives are continuing their investigation as they await the results and will coordinate with the Onondaga County District Attorney's Office when the results are available."

For now, Thompson remains in jail on the assault and weapons charges.

Syracuse police ask anyone with information about the shooting to call the Criminal Investigations Division at (315) 442-5222 or use the "SPD Tips" app.
